Sensorless Brushless DC Motor Reference Design

This reference design provides a hardware and
software solution for Sensorless Brushless dc motors.
This document includes complete schematics, printed
circuit board layout, and firmware. The Sensorless
Brushless dc motor reference design may be used as a
starting point for motor control system designers using
Silicon Laboratories MCUs, significantly reducing the
design time and time to market.

Brushless dc motors consist of a permanent magnet
rotor with a three-phase stator winding. Brushless dc
motors evolved from conventional dc motors where the
function of the brushes is replaced by electronics.
Brushless dc motors offer longer life and less maintenance than conventional brushed dc motors.
